MASONS POINTING-TOOL.

Specification of Letters Patent.

Patented May 28, 1907.

Application filed February 8, 1907. Serial No. 356,368-

To all whom it may concern.-

Be it known that I, ARENT EIDE, a subject of the King of Norway,residing at Knox, in the county of Benson and State of North Dakota,have invented certain new and useful Improvements in Masons Pointing-Tools; and I do declare the followin to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the ac companying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

My invention relates to tools used by stone masons; and the object is toprovide a pointing tool of such improved construction that it will holda charge of pointing mortar and feed it into thegroove of the toolbywhich the seams of a stone wall is pointed. This object I attain bythe novel oonstru ction and arrangement of parts illustrated in theaccompanying drawing, in which Figure 1 is a side elevation of myimproved pointing tool. Fig. 2 is a front end elevation of the toolshowing slight modifications. Fig. 3. is a sectional top view on theline a a in Fig. 2 with some further modifications.

Referring to the drawing by reference numerals, 1 designates the regularpointing tool, having a handle 2, and a groove 3 by which to form aslightly outward bulging seam or line of pointing mortar; the lattermaterial being usually white or of some other color giving the wall aneat appearance. To feed such mortar gradually into the groove while thetool is drawn along the stone wall, I provide the tool with a feedopening or port 4 and a cylinder 5, piston 6 and piston-rod 7. Thecylinder mayhave the mortar filled into it through a side opening 8while the piston is raised above said opening, or the filling may bedone through the top by using a detachable cover 9 having notches 10engaging catches 11 of the cylinder, or other suitable holding means.

Near the handle is pivoted at 13 to a projection 12 a lever 14, whosefront end is connected by a link 15 to the piston rod. Another link, 16,connects the lever with a trigger 17, which is normally held elevated bya spring 18. Said trigger or finger-lever is pivoted to the handle at19, and formed with a finger catch adapted to be operated by theforefinger of the hand holding the handle. It also has a thumb presser21 for those preferring to use the thumb, and if the operators hand isavery large one the thumb may be applied to the upturned end 22 of thelever 14. In this way I accommodate the different persons taste and sizeof hand with a simple mechanism, part of which may be omitted in themanufacture where so desired, especially in making an extra cheap gradeof the tool.

In using the tool the mortar is put into the cylinder as alreadydescribed, and as the operator draws the tool along the stone wall hepresses the piston downward by lever 14, piston rod 7 and piston 6,operated as described, whereby the pointing mortar escapes through thepart 4 and fills constantly the groove 3 forming the pointing seam orridge; as soon as the operator releases the lever 14 from pressure byhis finger or thumb the spring 17 exerts an upward pulling on thepiston, whereby the mortar is fully released from pressure and will notescape accidentally.

As for modifications, the detachable cover 9, already described, isomitted in Fig. 2,

'the top being fixed. The wearing collar 23 may be used to guide thepiston rod. In Fig. 3 is shown how the cylinder may be flattened some,like 5*, to get easier into nar row places or near upto a cap stoneetc., with the tool. The lever 14 may be single as in Fig. 1 or have itsend bifurcated as in Figs. 2 and 3, so as to divide the strain upon bothsides of the piston rod. In Fig. 1 the piston is shown in threepositions 6, 6 and 6 which indicate its entire movement and its beingabove the inlet opening when raised. extra high up.

Having thus described my invention, what I claim is 1. A pointing toolhaving a handle and a groove or face adapted to do the pointing, and aport adapted to feed mortar into the groove, a cylinder opening into theport, a piston rod and piston in the cylinder and a finger-operatedlever pivoted near the handle and operatively connected with the pistonrod, and a spring tending to raise the piston.

- 2. A pointing tool having a handle and a groove or face adapted to dothe pointing, and a port adapted to feed mortar into the groove, acylinder opening into the port, a

iston rod and iston in the cylinder and a finger-operatedeyer pivotednear the handle and operatively connected with the piston rod, a triggerpivoted near the handle and a ICC link connecting it with thefinger-operated lever, said triggenhaving touching points for theforefinger and for the thumb of the hand holding the handle.

3. A pointing tool having a handleand a groove or face adapted to do thepointing, and a port adapted to feed mortar into the groove, a cylinderopening into the port, a piston rod and piston in the cylinder and a IOfinger-operated lever pivoted near the handle and operatively connectedwith the piston rod, a trigger pivoted near the handle and a linkconnecting it with the finger-operated lever, saidv trigger havingtouching points for the forefinger and for the thumb of the hand holdingthe handle, and a spring tending to raise the piston.

In testimony whereof I aflix my signature, in presence of two witnesses.
